Manduka Pro...easy to break-in
The day I received my mat, I took it outside and scrubbed it with copious amounts of course Kosher salt and a regular kitchen towel. I spent a good 15-20 minutes rubbing it down with decent pressure. I rinsed the mat with a hose, let it dry for 2-3 hours and gave it a spin. It is now plenty grippy and good to go! I used it the next morning, and having previously used a $20 mat, I LOVE the cushion and the stability! I didn't know what a good mat should feel like until I tried my new mat. Truly, an exceptional item.
